The unusual association of multiple myeloma and visceral leishmaniasis has been poorly documented in the medical literature, and the presented case constitutes the first occurrence reported in Morocco. The patient, a 49-year-old man, was diagnosed with both conditions simultaneously. This rare coexistence raises intriguing questions about the underlying immunological mechanisms and interactions between the two diseases. In this particular case, the implementation of a therapeutic protocol combining specific antiparasitic treatment and chemotherapy for multiple myeloma led to promising results. The patient's progress was marked by a notable improvement in his health, highlighting the importance of an integrated approach to treating these competing conditions. This clinical case also highlights the importance of awareness and vigilance in detecting combinations of rare pathologies, paving the way for a better understanding of the complexity of concomitant diseases and more targeted treatment strategies.

Abstract: Leishmaniases in Morocco are endemic diseases. Three forms of leishmaniasis are reported, visceral leishmaniasis, cutaneous leishmaniasis caused by Leishmania tropica and cutaneous lesions due to Leishmania major. Leishmania infantum, a common parasite inducing visceral leishmaniasis, was observed thereafter in cutaneous lesions. The first case of cutaneous leishmaniasis due to L. tropica was isolated since 1987. But, this parasite was shown to be more polymorphic with almost 8 zymodemes. However, these zymodemes are not all transmitted by Phlebotomus sergenti and not all isolated from human reservoir. Regarding the clinical aspect, cutaneous leishmaniasis with L. tropica is described as a single lesion starting as a nodule at the site of inoculation. A crust develops centrally which may fall away exposing an ulcer which heals gradually. The second cutaneous form is that caused by Leishmania major. It was known in villages located in the southern slopes of the Atlas Mountains. Clinically, the lesion is often severely inflamed and ulcerated and heals in 4–6 months. The epidemiologic cycle of this rural form, include Phlebotomus papatasi as the proven vector and a commensally rodent, Meriones shawi grandis as the reservoir. However, visceral leishmaniasis in Morocco has been known since 1921. It is especially located in the North. The responsible parasite is L. infantum MON 1. Two species of the sand fly are involved in the transmission of this form, P. ariasi and P. perniciosus. In infected man, the clinical signs are non-tender splenomegaly, with or without hepatomegaly, wasting and pallor of mucous membranes. Even though L. infantum MON1 is responsible of the disease, some canine cases were reported to be caused by Leishmania tropica. [Copyright &y& Elsevier]

Abstract: Infantile visceral leishmaniasis (IVL), or Kala Azar, is a parasitic disease caused by the proliferation of a protozoan parasite Leishmania in the reticulo-histiocyte system. It is characterized by its geographical distribution most frequently in the Mediterranean area, India, East Africa and South America. In Morocco, during these last years, we are witnessing a significant recrudescence mainly in young child. The authors performed a retrospective study of 209 cases of visceral leishmaniasis admitted to the service of pediatrics at the University Hospital of Fez (CHU Hassan II) during a six-year period from January 1998 to December 2004. The average age of our patients is 3.7 years and boys are more affected (sex-ratio=1.45) 90% of the cases come from the suburbs of Fez, primarily from Taounate. The average time of consultation is 2.26 months. The main reasons are abdominal distension (68%), fever (94.5%) and the paleness (50%); rarely a hemorrhagic syndrome (8.5%). The clinical examination shows anaemia in 90% of the cases, fever in 92.6% of the cases and splenomegaly in 97.66% of the cases. The diagnosis is confirmed by the myelogram and the serology of leishmaniasis in 91.3% of the cases. Average diagnosis time is eight days. The identification of the parasite is achieved in collaboration with the Pasteur Institute of Casablanca and Leishmania infantum zymodeme-1 is detected in 100% of the cases. The treatment is based on glucantime at the dose of 80 to 100 mg/kg per day during 21 to 30 days and is efficient in 95.57% of the cases. We deplored six deaths which occurred due to malnutrition and probably in association with a macrophage activation syndrome. Infantile visceral leishmaniasis is the most frequent zoonosis in Morocco. Fez and its suburbs are an area of high endemicity. Its eradication must initially be based on improving socioeconomic conditions as well as fighting against malnutrition, which is a risk factor.

Chronic obstructive pulmonary disease (COPD) is a common respiratory disorder. Its exacerbation is infectious in more than half of the cases: with viral priority, while parasitic causes remain exceptional. In this work, we report a case of a COPD exacerbation caused by a visceral leishmaniasis (VL) complicated by a macrophage activation syndrome in an adult living in a Moroccan non-endemic region for this of leismaniasis form. In such atypical clinical feature, the diagnosis of VL was based on the myelogram after presence of peripheral cytopenia. Despite the seriousness of these pathologies, the early and specific treatment of VL allows a quickly improvement in the disorders caused by these diseases., (Copyright © 2018 SPLF.
